Regardless of the efforts of Israel or its closest ally, the United States, to prevent the International Criminal Court from seeking justice for the Palestinians and international aid workers killed and wounded in Gaza, the Court has a duty to at least open an investigation. The credibility of the ICC hangs in the balance. No individual who violates international law should escape justice. If Israeli officials are not investigated for possible war crimes in Gaza, then the tragic lessons learned from the last century about failures in international criminal justice and the consequences of inaction will have been in vain.
